IMPROVEMENT IN MORTAR AND BRICK ELEVATORS.

Specification forming part of Letters Patent No. [72,950, dated February1, 1876; application filed January 3, 1876. I

To all whom it may concern Be it known that I,FIELD11\IG BARNETT, ofJacksonville, in the county of Morgan and State of Illinois, haveinvented certain new and useful Improvements in Mortar and BrickElevators; and I dohereby declare that the following is a full, clear,and exact description thereof, which will enable others skilled in theart to which it appertains to make and use the same, reference being'hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification, in which- Figure 1 isa plan view, and Fig. 2 a side elevation, of myimproved elevator. aperspective view of one of the carriers; and Fig. 4 is a similar view ofa section of the track or ladder, with notched levers or dogs,

which engage with projections upon the carriers,'to retain the latter inan elevated position.

Corresponding parts in the several figures are denoted by like letters.

This invention relates to a certain improvement in that class ofelevators especially adapted to elevating mortar and bricks used forbuilding purposes; audit consists of a double track, traveled by carsoperating conjointly and retained alternately in an elevated position,all substantially as hereinafter more fully described and claimed.

In theannexed drawing, A A refer to a double track or ladder, traveledby cars B B,

united together by a rope, chain, or other medium, O, passing around apulley, D, secured in any known way to the upper end of the track orladder. A rope, 0, passes around a 'circumfercntially-grooved disk, d,of the pulley D, after which it is crossed and passed over frictionalrollers 00 in the pulley-frame f, and down to and around a pulley, g,near the. foot of the ladder or track. The object of this rope is toenable the laborer .or man descending in the emptied car to control thespeed of his descent.

The weight of the descending car and its occupant will elevate theloaded car to the de- Fig. 3 i5 it upon the cars, with which the saidcatches engage.

To free the catches h h from the projections M, to allow the'car or carsto descend, bear upon their chamfered or pivoted ends, when their freeor opposite ends will be liberated.

Stops h h are provided to keep the projecv tions '5 i in the notches ofcatches h h. v

Projections jj extend from the upper portion of the cars B B, to receiveand hold the hods E E, which carry the mortar, 850. The cars aresupplied with frictional rollers.

The catches h h may be adjusted to any point upon the ladder or track atwhich it is desired to unload the cars, as may also the pulley D withits frame f.

To prevent the slipping of the elevating or hoisting rope 0 upon thepulley D, its periphery maybe supplied with V- shaped bars.

The cars B B are extended, as shown at b b, to provide platforms for theman or laborer to stand upon descending with the car.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1S

.1. The double track or ladder AA, having the elevating or hoistingmechanism 0 D and. catches h h, in combination with the cars B B, havingthe projections ii, substantially as and for the purpose set forth.

2. The track or ladder A A, having the catches h h and stops h h, incombination with the cars B B, having the projections it,

substantially as and for the purpose set forth. 3. The-cars B B, havingthe extensions or platforms b b and hod-supporting project-ions j j,substantially as and for the purpose set" forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses. j
